The sixth riddle is here. I think this is another easy one, don’t you ?

My first is in fish but not in snail, My second is in rabbit but not in tail. My third is in up but not in down, My fourth is in ice cream but not in crown. My fifth is in tree you plainly see. A nature food for you and me. What am I?

This riddle will finish next Sunday 19th April
